FIG. 2 is a block diagram for a controller 120 of an embedded device 100 shown in FIG. 1.

Referring to FIG. 2, the controller 120 may include an interface 210, a processor 220, an error correction code (ECC) unit 230, a power management unit (PMU) 240, an interface 245 and a memory 260.

The interface 210 may provide an interface between the controller 120 and the memory unit 110 to allow the controller 120 to control the memory unit 110 in response to a request from the host device 200. The interface 210 may generate control signals for the memory unit 110 and process data under the control of the processor 220. When the memory unit 110 is a flash memory such as a NAND flash memory, the interface 210 may generate control signals for the NAND flash memory 110 and process data under the control of the processor 220.

The processor 220 may control general operations of the embedded device 100, and a write operation or a read operation for the memory unit 110, in response to a write request or a read request from the host device 200.

The interface 245 may process commands and data provided from the host device 200, and may communicate with the host device 200 through any one of various interface protocols. In some embodiments, the interface 245 may provide an interface between the embedded device 100 and the host device 200 through a serial connection. For example, the interface 245 may provide the interface in accordance with an automation/drive interface transport (ADT) protocol.

The memory 260 may serve as a working memory of the embedded device 100 and the controller 120, and store data for driving the embedded 100 and the controller 120. The controller 120 may control the memory unit 110 in response to a request from the host device 200.

FIG. 3 is a block diagram illustrating an embedded system 20 including an embedded device 150 and a host device 250 in accordance with an embodiment of the present disclosure. In examples of the invention, the embedded system 20, embedded device 150 and host device 250 may be similar in construction and functionality as embedded system 10, embedded device 100, and host device 200 respectively, as described with reference to FIGS. 1 and 2.

Referring to FIG. 3, the embedded system 20 may provide the ability to use common, industry standard connections to manage or otherwise communicate with the embedded device 150 through a serial interconnection. This technique may allow the embedded device 150 to use this common, ubiquitous infrastructure for management and monitoring.

The embedded system 20 may enable a service on the embedded device 150 such as a solid state drive (SSD) and use that service in an industry standard way through the internet. The embedded device 150 may be connected to the host device 250 through a serial interconnect. One or more service providers 311-312 may be located on the embedded device 150. The client for the service provided by the embedded device 150 may be located anywhere on a network (i.e., the internet) where the device is visible. In some embodiments, as shown in FIG. 3, the client 440 may be located in the host device 250. Alternatively, the client 440 may be located on the internet (not shown) connected through the host device 250.

The embedded device 150 may include a plurality of service providers (e.g., two service provides) 311-312, a processing unit 320 and an interface unit 330.

Each of the service providers 311-312 may provide a packet for a service. Examples of services for the embedded device 150 such as the SSD may include a load profile service, drive health monitor, capacity used monitor, bad block count profile, end of life alert service, drive configuration service or any type of SMART counter harvesting service.

The interface unit 330 may be coupled to the processing unit 320, and may transmit a transmission control protocol (TCP) segment generated by the processing unit 320 to the host device 250. The interface unit 330 may be a serial interface for a serial interconnect between the embedded device 150 and the host device 250. In some embodiments, the interface unit 330 may be implemented with a serial interface based on an automation drive interface-transport (ADT) protocol.

The processing unit (modified TCP stack) 320 may present an industry standard transmission control protocol (TCP) interface to any service providers 311-312. For outgoing TCP packets, the processing unit 320 may do the job of a typical TCP stack except that it uses the ADT layer rather than an internet protocol (IP) layer it would normally use. In other words, the processing unit 320 may do the job of a modified TCP stack. In detail, the processing unit 320 may generate a TCP segment corresponding to the packet for the service. In some embodiments, the packet may be divided some pieces, and the TCP segment may include a piece of the packet and a header with no checksum value.

The host device 250 may include an interface unit 410, a first processing unit 420, a second processing unit 430, and at least one of a third processing unit 461 and a fourth processing unit 462. Furthermore, the host device 250 may include a client 440 and a host TCP stack 450.

The interface unit 410 may receive the TCP segment generated by the processing unit 320 of the embedded device 150. The interface unit 410 may be a serial interface for a serial interconnect between the embedded device 150 and the host device 250. In some embodiments, the interface unit 410 may be implemented with a serial interface based on an automation/drive interface-transport (ADT) protocol.

The first processing unit 420 may perform a TCP check summing operation for the TCP segment received from the embedded device 150 through the interface unit 410 to calculate the checksum value based on the TCP segment and generate a new TCP segment including a header with the checksum value. In other words, the first processing unit 420 may do the job of a modified TCP check. Further, the first processing unit 420 may connect the new TCP segment to the second processing unit 430 for IP routing.

The second processing unit 430 may perform the IP routing for the TCP segment generated by the first processing unit 420. Since the embedded device 150 resembles any host on the internet with its own IP address and its own set of services, the second processing unit 430 may perform the IP routing. If the client is located in the host device 250 as the client 440, the second processing unit 430 may perform the IP routing toward the client 440 through the host TCP stack processing unit 450. If the client is located on the internet through the host device 250, the second processing unit 430 may perform the IP routing toward the third and fourth processing units 461-462.

Each of the third and fourth processing units 461-462 may receive the TCP segment generated by the first processing unit 420 from the second processing unit 430, and generate an internet protocol (IP) packet based on the TCP segment generated by the first processing unit 420. Furthermore, each of the third and fourth processing units 461-462 may generate a transmission frame based on the IP packet, and transmit the transmission frame to the network (i.e., Ethernet).

As shown in FIG. 3, the interface units 330 and 410 as the industry standard ADT transport layer may be implemented on either side of the serial link. This transport layer is described in the committee T10 document for small computer system interface (SCSI) over Serial. The transport layer implements a scheme by which the link runs as fast as both sides can handle and guarantees lossless delivery of the data.

The processing unit 320 as the modified TCP stack may reside on the embedded device 150, and present an industry standard TCP interface to any service providers 311-312 present in the embedded device 150. For outgoing TCP packets, the processing unit 320 does the job of the typical. TCP stack except that it uses the ADT layer rather than the IP layer. The processing unit 320 does not perform TCP check summing to guarantee lossless delivery of the packet, which relieves the embedded device 150 of this computation intensive job. Furthermore, the processing unit 320 also does not perform TCP checksum testing on incoming packets. This also relieves the embedded device 150 of this computation intensive job. Instead, all of the TCP check summing is done on the processing unit 420 as the Modified TCP check component present on the host device 250 of the serial link. The host device 250, which typically has much more computing power than the embedded device 150, is therefore responsible for the TCP check summing. The processing unit 420 as the modified TCP check component is also responsible for connecting to the processing unit 430 for the IP routing of the host device 250. This means that IP routing in an industry standard way may be used The embedded device 150 may look like any host on the Internet with its own IP address and its own set of services.

Although the modified TCP stack of the embedded device 150 does not perform TCP check summing or TCP checksum testing, the interface units 330 and 410 as the ADT layer may guarantee error free transmission. The interface units 330 and 410 may handle and correct bit errors generated on the link. Essentially, this is a reliable IP layer that a typical TCP assumes does not exist, hence the lightweight nature of the modified TCP stack 320 on the embedded device 150.

Embedded systems have fewer input/output (I/O) connections and processing resources compared to other systems. Embodiments of the present invention may include a serial connection between the embedded device 150 and the host device 250 which uses fewer I/O connections than Internet protocols such as TCP/IP or user datagram protocol/internet protocol (UDP/IP), but still offers high bandwidth access to the embedded system 20. Also, the embedded device 150 does not perform TCP checksum generation or TCP checksum checking, which reduces the processing load on the resource limitations of the embedded device 150. For these reasons, the embodiments of the present invention may offer an advantageous process of managing a service running on an embedded system that works within the constraints of an embedded system's I/O limitations and processing limitations.

Since the embedded device 150 may be guaranteed to be an endpoint with no possibility of forwarding IP packets through the embedded device 150, no packet routing tables or any type of IP routing are required on the embedded device 150. This also saves considerable computing resources.

In some embodiments in order to obtain the appropriate information used by the reporting or monitoring service, commands are sent to the embedded device 150 (e.g., SSD) via the host interface to harvest a set of industry standard statistics (e.g., SMART counters). Embodiments herein may make the embedded device 150 visible on the internet through a serial interface (e.g., as opposed to a host interface). The embedded device 150 then may host services that appear like any other services one would expect to find. Special clients written in any internet language such as Java can connect to these drives of the embedded device 150 and manage them through the normal local area network (LAN) in a datacenter.

In some embodiments, an embedded system may include a high speed universal asynchronous receiver/transmitter (UART). In some embodiments, the TCP time service may be used to synchronize time between the host device 250 (e.g., data center) and the embedded device 150 (e.g., SSD). This would, for example, be very valuable to the device to assist in determining downtime and age.

FIG. 4 is a diagram illustrating a TCP/IP model of an embedded system in accordance with an embodiment of the present disclosure. The TCP/IP model may be performed by the embedded device 150 and the host device 250 in FIG. 3 and/or the embedded device 100 and the host device 200 in FIGS. 1 and 2.

Referring to FIG. 4, the TCP/IP model may include an application layer 401, a transport layer 402, an Internet layer 403 and a network interface layer 404. The application layer 401 may be performed or implemented by the embedded device 150. The transport layer 402 may be performed or implemented by the embedded device 150 and the host device 250. The Internet layer 403 and a network interface layer 404 may be performed or implemented by the host device 250.

At the step 470, each of the service providers 311-312 of the embedded device 150 may provide a packet for a service. Examples of services for the embedded device 150, such as the SSD, may include a load profile service drive health monitor, capacity used monitor, bad block count profile, end of life alert service, drive configuration service or any type of SMART counter harvesting service.

At the step 475, the processing unit 320 of the embedded device 150 may do the job of a modified TCP stack. In detail, the processing unit 320 may generate a TCP segment corresponding the packet for the service. In some embodiments, the packet may be divided into pieces, and the TCP segment may include a piece of the packet and a header with no checksum value.

At the step 480, the interface unit 330 of the embedded device 150 may transmit a transmission control protocol (TCP) segment generated by the processing unit 320 to the host device 250.

At the step 485, the first processing unit 420 of the host device 250 may perform a TCP check summing operation for the TCP segment received from the embedded device 150 through the interface unit 410 to calculate the checksum value based on the TCP segment, and generate a new TCP segment including a header with the checksum value.

At the step 490, the second processing unit 430 of the host device 250 may perform the IP routing for the TCP segment generated by the first processing unit 420. Furthermore, each of the third and fourth processing units 461-462 may receive the TCP segment generated by the first processing unit 420 from the second processing unit 430, and generate an internet protocol (IP) packet based on the TCP segment generated by the first processing unit 420.

At the step 495, each of the third and fourth processing units 461-462 of the host device 250 may generate a transmission frame based on the IP packet, and transmit the transmission frame to the network (i.e., Ethernet).

FIG. 5 is a diagram illustrating an operation of generating TCP segments in accordance with an embodiment of the present disclosure. For example, the operation of generating TCP segments may be performed by the processing unit 320 of the embedded device 150.

Referring to FIG. 5, the processing unit e.g., processing unit 320) may receive a packet or an application layer data 510 for a service from the service providers (e.g., service providers 311-312), The processing unit may generate a TCP segment corresponding the application layer data 510 for the service. In some embodiments, the application layer data 510 may be divided some pieces (Piece 1-Piece 3) 520, and each of the TCP segment 530 may include a piece of data 534 and a header 532 with no checksum value. For example, the TCP segment 1 may include a piece Piece 1 and a header Header 1, the TCP segment 2 may include a piece Piece 2 and a header Header 2 and the TCP segment 3 may include a piece Piece 3 and a header Header 3.

FIGS. 6A and 6B are diagrams illustrating structures of transmission control protocol (TCP) segment headers in accordance with an embodiment of the present disclosure. For example, the TCP segment header 532A of FIG. 6A may be generated by the processing unit 320 of the embedded device 150, and the TCP segment header 532B of FIG. 6B may be generated by the processing unit 420 of the host device 250. Since the fields of the TCP headers are well known, the detailed description regarding the fields of the TCP headers will be omitted.

Referring to FIG. 6A, the TCP segment may include a header 532A with no checksum value and a data 534. The TCP segment header 532A may include a source port number, a destination port number, a sequence number, an acknowledgement number, a length, flags, a window size, an urgent pointer, a reserved filed and an option field.

Referring to FIG. 6B, the TCP segment may include a header 532B with TCP checksum value 600 and a data 534. The TCP segment header 532B may include the source port number, a destination port number, a sequence number, an acknowledgement number, a length, flags, a window size, a TCP checksum value 600, an urgent pointer, a reserved filed and an option field. In contrast to the TCP segment header 532A, the TCP segment header 532B further includes the TCP checksum value 600.

With such a system in place, it may take full advantage of industry standard internee security protocols, multiple; ports for multiple services and potentially define a whole new set of products to manage our hardware in a data center.
